Let C(x) be the cost to produce x batches of widgets, and let R(xp be the revenue in thousands of dollars. Complete parts (a) through (d) below.

R(X) 12x, C(x) x+ 10

(b) Find the minimum break-even quantity.

Using the expressions -x2 12x and/or x+ 10, identify an equation to be solved in order to find the minimum break-even quantity.

The minimum break-even quantity is:

(Simplify your answer.)
